Buying a battery-powered lawn mower: self-propelled or not? (Need answer fast!)

My Ryobi battery mower experience du jour…

I got it (non self propelled but 40v) out to mow the lawn. Started it, went a couple feet, and it died. What? Started again, pushed a bit, and it died again. OK what’s going on? It wasn’t struggling…and we have LOTS of Ryobi tools. When that battery isn’t strong enough, it’s just done. No sputter, no slow down, nothing—it’s just done.

Those extending arm handle things need to be locked…played around with that. Same thing…ran a short while, stopped.

Came in and checked youtube. I found this:

Tightening those six screws as he said seems to have fixed the problem. He also says his video might be a warning to those who haven’t yet bought one to think twice.

Ours is about a year old. I think those screws came loose because it isn’t self propelled and I have to wrangle it some. But they seemed a bit loose after I finished as well.

My WAG is that when they get loose something gets misaligned or whatever, causing it to cut off for safety’s sake.
